Huh. One of the biggest 'drawbacks' of using AWS as a production platform is that making your development environment look like production is hard.

Having to deploy to test is cumbersome and having a cost associated with each test can definitely introduce some sort of 'stress' and encourage people to not test incrementally.

I wonder if this changes that. Having services like S3, Lambda and SQS available locally sounds super interesting.

I will definitely keep an eye on this. One other thing I would like to see is CloudFront, which can be very hard to start with due to its opaqueness. Having to wait 20+ minutes between configuration changes is very demotivating.
